Is this normal?

Hi guys,
Please forgive me as i am still sorta new to keeping fish and all.

So i was giving charlie his exercise (mirror) and i noticed that his tail looks sorta blackish. Whats up?
Picture 1 is with the flash.
Picture 2 is without the flash.

In picture 2 the blackness is very apparent. It is sorta hard to see, i know, but please bear with me here.

Please tell me if the pictures don't show up

nice colored fish by the way, but the blackish coloring in his tail looks like part of his normal coloring..so i would not worry

Thank you! He has quite the personality he does but he is beautiful, i agree.

Thanks for telling me that it is probably normal. I have been worrying about it for a while.
